Manning did not appear to be in any discomfort during the portion of practice open to the media. He went through his drills as usual and was not wearing any visible brace or wrap.

Manning spent extra time in the training room after Sunday's game, saying that he was icing down "wear and tear" on his body. He was hit several times by Titans defenders, most significantly on a fourth-quarter deep pass that fell incomplete to Odell Beckham Jr.

Coughlin said he was unsure of how the injury took place. Backup quarterback Ryan Nassib handled the final two snaps of the blowout.

Coughlin said Manning was able to complete his usual Tuesday routine that included mostly film study and preparation for the upcoming game. He also did his usual weight-lifting, although Coughlin joked about the intensity of that workout.

"He squatted 450, benched 275," Coughlin said with a smile.

Obviously it's something Coughlin can make light of, and there is no reason to think Manning will miss Sunday's game against Washington. He's started 164 straight regular season games for the Giants, the longest active streak of any player in the NFL and the third-longest streak ever for an NFL quarterback.

"He'll practice like he always practices," Coughlin said, "unless I hear something different from him. All I know is it's his back and he functions well. But for reasons, whatever, he's on the list."
